Objective: This is a prospective study examining palatal casts from patients with unilateral cleft lip and palate (UCLP) in the first month of life, immediately before cheiloplasty, and immediately before palatoplasty. None of the patients receives presurgical orthopedics (nasoalveolar molding). Design: In this prospective study, upper arch plaster models were taken 3 times during the treatment: in the first month of life (T1), before the cheiloplasty (T2), and before the palatoplasty (T3). Anatomic landmarks were defined and linear anthropometric measurements were obtained afterward. Dimensional analysis was performed using 3D software. Two-way analysis of variance followed by Tukey test was performed for statistical analysis. Setting: Tertiary, institutional. Participants: Twelve patients with UCLP of either sex with less than 1 month of life and without any other syndrome. Intervention: No intervention was performed. Main Outcome Measure: Reduction of the cleft without using orthopedics apparatus. Results: There was a statistically significant reduction in the cleft gap comparing T1 to T3. There was also a significant reduction in the intercanine width comparing T2 and T3, and T1 and T3. There was significant increase in the posterior arch width comparing T2 and T3, and T1 and T3. The palatal plate’s width increased in all times analyzed. Conclusion: The palatal cleft narrows spontaneously as well in both midpoint and posterior point during the first 6 months of patient’s treatment. This event was enhanced by cheiloplasty. This surgery might have a greater influence on the anterior arch width than in the posterior arch region.

ResumoOs cistos epidermoides constituem lesões congênitas, benignas e raras, que correspondem a cerca de 0,2% a 1,8% de todos os tumores intracranianos, sendo que em apenas 5% dos casos localizam-se no quarto ventrículo. Apesar de sua gênese na vida intrauterina, são geralmente diagnosticados entre a terceira e quinta década de vida em decorrência de seu padrão de crescimento muito lento. A imagem ponderada pela difusão da ressonância magnética é fundamental para a formulação do diagnóstico. O tratamento ideal consiste no esvaziamento do conteúdo cístico com ressecção completa da cápsula. Neste trabalho, é descrito um caso de uma paciente de 31 anos de idade com síndrome cerebelar, evoluindo com síndrome de hipertensão intracraniana. A sintomatologia era decorrente de hidrocefalia obstrutiva por cisto epidermoide localizado no interior do quarto ventrículo, confirmado pela anatomia patológica. Keywords► epidermoid cyst ► fourth ventricle ► hydrocephalus AbstractEpidermoid cysts constitute congenital, benign and rare lesions, corresponding to approximately 0.2 to 1.8% of all intracranial tumors. Only 5% of cases located in the fourth ventricle. Despite its genesis in intrauterine life, are usually diagnosed between the third and fifth decade of life due to its very slow growth pattern. The imagem weighted by the diffusion of the magnetic resonance is essential to formulation of the diagnosis. The ideal treatment of choice is the empyting of the cystic contente with complete capsule ressection. In this work the case of a 31-year-old female with cerebelar syndrome evolving with intracranial hypertension. The symptomatology was due to obstructive hydrocephaly by an epidermoid cyst located inside the fourth ventricle, confirmed by the pathological anatomy.
